Title: Denitration control device for engine exhaust gas
Inventor: SHIBAHARA ATSUSHI
IPC: F01N9/00
Filed: 1991-02-20
Abstract: PURPOSE:To control reducing agent used for a denitration device by carrying out fuzzy inference in a diesel engine, etc. CONSTITUTION:Concentration of nitrogen oxide (NOx) in exhaust gas of a diesel engine 1 is detected by a detector 2. An ammonia (NH3) amount as reducing agent is found out by an arithmetic unit 3 on the basis of concentration of nitrogen oxide detected by the detector 2. The change rate of concentration and the difference between a target concentration of nitrogen oxide and the detected concentration, are calculated on the basis of the difference between the concentration of nitrogen oxide detected at the time of the preceding sampling and the concentration of nitrogen oxide. And, fuzzy inference is carried out while those change rates and the difference are served as input variable, and the control amount of ammonia according to the change of the concentration of nitrogen oxide is found out. Furthermore, an ammonia injection device 4 is controlled together with the ammonia amount so as to reduce nitrogen oxide in exhaust gas.

Title: Stress corrosion cracking testing liquid
Inventor: TSURUTA TAKAO
IPC: G01N3/18
Filed: 1983-02-22
Abstract: PURPOSE:To enhance reproducibility while reducing the production cost of the titled liquid, by dissolving sodium thiosulfate in water to form an aqueous solution of which the pH is, in turn, adjusted to 3 or more. CONSTITUTION:Sodium thiosulfate is dissolved in water to prepare an aqueous solution of which the pH is adjusted to 3 or more to form the titled testing liquid. The upper limit of the pH is not specially set but, because the pH is almost 8 when no sulfuric acid is added, the pH is pref. 3-8. The concn. range of sodium thiosulfate is pref. 0.001-0.1mol. Because sodium thiosulfate is oxidized by oxygen dissolved in the liquid from the atmosphere and polythionic acid is naturally formed, the formed liquid has the same corrosiveness as a conventional gas blowing method.

Abstract: PURPOSE:To eliminate any variation in a floating value of a wafer as well as to make an excellent, nondistortion mirror securable, by detecting a load current of a polisher driving motor, while adjusting a vertical position of the wafer so as to make this load current constant. CONSTITUTION:A variation in a load current of a polisher driving motor 21 is detected by a detector 23, and this signal is transmitted to a comparator 24, comparing it with the setting value. In consequence, when it is a more shifted value than the setting value, a signal is transmitted to a controller 25, and a vertical motor 26 is driven according to size of this signal whereby a vertical position of a wafer 7' on a polisher 1' is adjusted via an up-down rod 27 and a support rod 10'. With this adjustment, a gap between abrasive cloth 2' and the wafer 7' is compensated, making it a fixed value, thus mirror finishing for the wafer 7' takes place without entailing any distortion.

Abstract: PURPOSE: To dispense with any complicate pressure applying mechanism, by which sealing members are interposed to be made close, by making amounts of thermal expansion of fasteners for a gastight container, which is used at high temperatures, larger than amounts of thermal expansion of parts being fastened such as flanges and the like. CONSTITUTION: A solid sealing material 15 is used and fastening is effected by means of fasteners such as bolts 12 or the like to join an upper container 3 and a lower container 2. At this time, coefficients of thermal expansion and thicknesses of a gastight container 1, the sealing material 15 and the fasteners 12 are suitably selected so that thermal expansion of parts being fastened is made larger than thermal expansion of the fasteners 12. Alternatively, thermal expansion of parts being fastened is made large by addition of spacers 17 which have a high coefficient of thermal expansion. Thus flanges 6, 7 of the gastight container, the sealing material 15 and the spacers 17 elongate more than the fasteners 12 do when temperature rises, so that a high thermal stress generates on fastened parts.  Accordingly, the fastened parts are made free of looseness due to heating to enable maintain gastightness at high temperature. Also, crystal growth and heat treatment are terminated, stresses decrease upon cooling and the fasteners are made easy to disengage.

Title: Device for preventing empty shooting fault in common use as overload safety device
Inventor: ORII TAKESHI
IPC: B30B15/28
Filed: 1984-02-16
Abstract: PURPOSE:To provide both effects of preventing overload and preventing an empty shooting fault to a titled device by making an oil storage means having a pneumatic chamber communicate with a hydraulic chamber, providing a pneumatic control means to the pneumatic chamber and changing the volume of an oil chamber. CONSTITUTION:When a die is overloaded, a cylinder 12 moves downward and the oil pressure in a hydraulic chamber 17 increases. When the lifting force of a plunger 27 exceeds the depressing force of a pneumatic chamber 31, the plunger 27 rises to expand the volume of an oil chamber 29 thus admitting the oil 18 in the chamber 17 into the chamber 29. The cylinder 12 is then lowered and the bottom dead point position of a slide 15 is raised. In the case of empty shooting, a control valve 32 is closed to stop the supply of the air pressure to the chamber 31 and the chamber 31 is opened to the atm. The force for depressing the plunger 29 is thereby lost and the volume of the chamber 29 is expanded so that the oil 18 in the chamber 17 flows into the chamber 29. Then the cylinder 12 descends with respect to the slide 15. The damage of the die is prevented by such mechanism.
